The Tri-Mod Wah is an evolutionary outgrowth of the original Hot Hand® Wah Filters system in a compact and accessible format. There are 11 Wah effects that range from Classic Wah through Low, Band Pass and Multipeak variations, that can all be further modified using either a Hot Hand motion controller, LFO (Low Frequency Oscillator) or Envelope Follower. All Soundblox effects pedals are compatible with the Hot Hand Motion Controller — available separately in wireless or wired configurations — or an extensive range of on-board controls. Soundblox pedals provide a wide variety of original sounding effects in a sleekly designed, rugged package that is easy to use and highly flexible.
